Definitions for network terms
APN (Access Point Name)
APNs are provided from the Airtime Provider. They may also be defined on the SIM card
The APN is used by the network user to establish a connection to the required external network.
This means that the terminal must know the APN in order to be able to connect to the external
network.
Header compression
The Header of a data packet contains control information belonging to that packet. The
information in the Header can take up a considerable amount of bandwidth. In order to save
bandwidth, you can use Header Compression, meaning you compress the header information,
leaving some of the information out.
You can select whether or not to use Header Compression for your data transmission.
• Header Compression enabled: Recommended for low-noise applications.
If you select Header Compression enabled, you will be using less bandwidth on header
information, leaving more bandwidth for the actual payload.
• Header Compression disabled: Recommended in noisy environments.
If Header Compression is disabled, the system will be less sensitive to noise.
Profiles
A profile is a collection of Quality of Service (QoS) settings and other settings defining the mode in
which data is transmitted on an interface. For example, a profile is used to define whether a
connection should be a Standard or Streaming connection.
You can select between a number of predefined profiles or define your own profiles for your data
transmission.
You need an administrator password to define profiles and traffic flow filters.
NAT (Network Address Translation)
NAT enables a local-area network to use one set of private IP addresses for internal traffic and an
assigned or static IP address for external traffic. The built-in NAT module in the terminal makes all
necessary address translations between the local-area traffic and the external traffic.
If more than one user is connected, you must select a network user group with Router mode to use
the NAT of the terminal.
Note
If you have selected more than one profile (one primary and one or more secondary
profiles) for an interface, you must define a traffic flow filter before you can establish a
valid connection.
